New guy, be gentle.

Found a D3 on Craigslist for a good price. Physically appears to be in good shape, but it's just the unit itself... no wiring included.  What would be the easiest way to power it up and check for functionality?  I'm generally skeptical when dealing with Craigslist so I'm just wanting to cover my @ss and not buy a dead unit.  

Didn't search, so my apologies if this is common knowledge somewhere.

Thanks!

Hi,

You'll need a 12V Power Supply and some probes or solid-wire.

You have to apply 12V to the 2 Pins in the lower Right and Ground to the upper right Pin of the Connector (Power Supply 10A) 

Now it should come alive.
